Description

In a conventional communication system, a receiving device transmits feedback (ACK)/(NACK) information to a transmitting device for different coding blocks in one transmission block. The transmitting device retransmits the coding blocks that have failed to be decoded based on the feedback information.

FIG. 1 illustrates a method for transmitting information in an embodiment of the present application. As shown in FIG. 1, method 100 includes steps S110 to S130.

At S110, the terminal device determines a first number of information, the first number of information being information related to the number of coding block groups included in one transmission block, and each coding block group includes at least one coding block.

At S120, the terminal device determines a second number of pieces of information, the second number of pieces of information being related to the total number of bits included in the currently scheduled transmission block.

At S130, the terminal device determines information related to the coding block group actually included in the currently scheduled transmission block based on the first number information and the second number information.

According to the method for information transmission in the embodiment of the present application, the terminal device determines information related to the coding block groups actually included in the currently scheduled transmission block based on information related to the number of coding block groups included in one transmission block and information related to the total number of bits included in the currently scheduled transmission block. As a result, the terminal device determines the number of coding block groups actually included in the currently scheduled transmission block based on information related to the coding block groups actually included in the currently scheduled transmission block, and when providing feedback to the coding block groups, determines an appropriate amount of feedback information based on the number of coding block groups, thereby reducing the overhead of control signaling and improving the demodulation performance of the control signaling and the system efficiency.

Optionally, in S110, the first number information indicates the maximum number of coding block groups that can be included in one transmission block, i.e., the first number information indicates the maximum number of coding block groups into which one transmission block is divided. In this case, the terminal device receives higher layer signaling from the network device and determines the first number information based on the higher layer signaling. Alternatively, the maximum number of coding block groups that can be included in one transmission block is pre-agreed.

Or, in S110, the first number information indicates the number of coding block groups actually included in the currently scheduled transmission block, or the first number information indicates the number of coding block groups into which the currently scheduled transmission block is actually divided. In this case, the terminal device receives downlink control signaling from the network device and determines the first number information based on the downlink control signaling.

Optionally, in S120, the second number information indicates the total number of bits included in the currently scheduled transmission block, or the second number information indicates the number of bits included in each coding block group in the currently scheduled transmission block. In this case, the terminal device receives signaling from the network device and determines the second number information based on the received signaling.

Optionally, in S130, the information related to the coding block groups actually included in the currently scheduled transmission block is the number of coding block groups actually included in the currently scheduled transmission block, or the information related to the coding block groups actually included in the currently scheduled transmission block is the number of coding block groups actually included in the currently scheduled transmission block and the number of coding blocks included in each coding block group.

Optionally, in some embodiments, the terminal device determines the number N of coding block groups actually included in the currently scheduled transmission block according to the following formula (1):
where min() denotes the operation of obtaining a small value, A denotes the maximum number of coding block groups that can be included in one transmission block,
denotes the number of coding blocks actually included in the currently scheduled transmission block, where
The value of may be instructed by the network device to the terminal device by signaling, or may be determined by the terminal device based on information of the second number.

For example, if the maximum number of coding block groups that can be included in one transmission block is 10 and the number of coding blocks actually included in the currently scheduled transmission block is 30, the terminal device determines 10 as the number of coding block groups actually included in the currently scheduled transmission block. If the maximum number of coding block groups that can be included in one transmission block is 10 and the number of coding blocks actually included in the currently scheduled transmission block is 8, the terminal device determines 8 as the number of coding block groups actually included in the currently scheduled transmission block.

Optionally, in some embodiments, the terminal device determining the number of coding blocks actually included in the currently scheduled transmission block based on the information of the second number is: the terminal device determining the number of coding blocks actually included in the currently scheduled transmission block based on the following formula (2):
Where:

In addition, in the formula (2),
The value of is pre-agreed or configured by the network device. In addition, if the terminal device supports multiple transmission configurations, the value of is determined according to the transmission configuration.
The values of are different. Then, the terminal device determines the
For example, if a terminal device supports multiple service types (such as Enhance Mobile Broadband and URLLC (Ultra Reliable & Low Latency Communication)), the value of
The values of , may be different, and/or the terminal device may support various types of transmission time intervals (e.g., slots, mini-slots, etc.) corresponding to different transmission time intervals.
The values of are different, and/or the terminal device supports various basic parameter sets (Numerology) and corresponds to different basic parameter sets.
The values are different.

moreover,
or if the number of coding block groups actually included in the currently scheduled transmission block is the maximum number of coding block groups that can be included in one transmission block, the terminal device

Alternatively, the terminal device may select N block groups that are actually included in the currently scheduled transmission block.

It is determined that the

for example,
, then the terminal device determines that, in the three coding block groups, two coding block groups include three coding blocks and one coding block group includes two coding blocks.

Furthermore, if the number of coding block groups actually included in the currently scheduled transmission block is the number of coding blocks actually included in the currently scheduled transmission block, each coding block group includes one coding block.

In an embodiment of the present application, it is optional, and the terminal device determines the number of coding block groups actually included in the currently scheduled transmission block and the number of coding blocks included in each coding block group based on the first number information and the second number information, and if the first number information indicates the number of coding block groups actually included in the currently scheduled transmission block, the terminal device determines the number indicated by the first number information as the number of coding block groups actually included in the currently scheduled transmission block. Furthermore, the terminal device determines the number of coding blocks included in each coding block group in the currently scheduled transmission block based on the second number information.

Selectable, for example, in each coding block group
where:
indicates the number of bits contained in each coding block group.

In the above embodiment, when a coding block group that is selectable and actually included in the currently scheduled transmission block includes multiple coding blocks, the numbers of the multiple coding blocks included in each coding block group are consecutive. As shown in FIG. 2, the currently scheduled transmission block includes three coding block groups, coding block group 1, coding block group 2, and coding block group 3, where coding block group 1 includes coding blocks numbered CB0, CB1, and CB2, coding block group 2 includes coding blocks numbered CB3, CB4, and CB5, and coding block group 3 includes coding blocks numbered CB5, CB6, and CB7.

Furthermore, as shown in Figures 3 and 4, the information carried in each coding block group corresponds to one common cyclic redundancy check (CRC) information, and the information carried in each coding block contained in each coding block group corresponds to one dedicated CRC information.

In an embodiment of the present application, when the selectable transmission block currently scheduled is a transmission block for downlink transmission, the terminal device determines the coding block group that has failed to be transmitted among the coding block groups actually included in the currently scheduled transmission block, and then determines the feedback information based on the coding block group that has failed to be transmitted.

Optionally, the feedback information indicates NACK information of the coding block group that has failed to be transmitted, and when the network device receives the NACK information, the network device can directly determine the coding block group that has failed to be transmitted based on the NACK information.

Or, the above feedback information indicates ACK information of correctly transmitted coding block groups, and the network device can determine the correctly transmitted coding block groups based on the ACK information, and further determine the unsuccessfully transmitted coding block groups.

Or, the feedback information includes ACK information and NACK information, and the network device directly determines the coding block group that has failed to be transmitted based on the NACK information.

This allows the terminal device to provide feedback to the coding block group, thereby reducing control signaling overhead and improving control signaling demodulation performance and system efficiency compared to a method in which feedback is provided to each coding block.

Specifically, in some embodiments, the terminal device determines which coding block groups have failed to be transmitted among the coding block groups actually included in the currently scheduled transmission block in the following two ways:

In method 1, the terminal device decodes all the coding blocks in one coding block group based on the dedicated CRC information corresponding to the information carried in each coding block, and if there is a coding block that has failed to be decoded in this coding block group, it determines that this coding block group is a coding block group that has failed to be transmitted.

In method 2, the terminal device checks the coding block group based on common CRC information corresponding to the information carried in one coding block group, and if the check of this coding block group fails, it determines this coding block group as a coding block group whose transmission has failed.

In an embodiment of the present application, when a selectable and currently scheduled transmission block is a transmission block for uplink transmission, the terminal device receives scheduling information, and the scheduling signaling indicates retransmission of some of the coding block groups within the coding block groups actually included in the currently scheduled transmission block, and then the terminal device retransmits the some of the coding block groups. In this way, the terminal device only needs to retransmit the coding block groups indicated by the transmission scheduling signaling, thereby improving system efficiency.

Above, the method for transmitting information in the embodiment of the present application from the terminal device side has been described with reference to Figures 1 to 4. Below, the method for transmitting information in the embodiment of the present application from the network device side will be described with reference to Figure 5. Note that the interaction between the network device and the terminal device on the network device side is the same as that on the terminal device side, and therefore will not be described here for the sake of brevity.

FIG. 5 illustrates a method for information transmission in another embodiment of the present application, and as shown in FIG. 5, method 200 includes steps S210 to S230.

At S210, the network device determines a first number of information, the first number of information being information related to the number of coding block groups included in one transmission block, and each coding block group includes at least one coding block.

At S220, the network device transmits a second number of pieces of information to the terminal device, the second number of pieces of information being related to the total number of bits included in the currently scheduled transmission block.

At S230, the network device determines information related to the coding block group actually included in the currently scheduled transmission block based on the first number information and the second number information.

According to the method for information transmission in the present application, the network device determines information related to the coding block groups actually included in the currently scheduled transmission block based on information related to the number of coding block groups included in one transmission block and information related to the total number of bits included in the currently scheduled transmission block. Furthermore, the network device transmits a second number of information to the terminal device, and the terminal device determines information related to the coding block groups actually included in the currently scheduled transmission block based on the determined first number and the received second number of information. In this way, the terminal device or the network device can determine the number of coding groups actually included in the currently scheduled transmission block based on the information related to the coding block groups actually included in the currently scheduled transmission block, and when feedback is performed on the coding block groups, an appropriate amount of feedback information is determined based on the number of coding block groups, thereby reducing the overhead of control signaling and improving the demodulation performance of the control signaling and system efficiency.

In an embodiment of the present application, the information related to the coding block groups actually included in the currently scheduled transmission block is the number of coding block groups actually included in the currently scheduled transmission block; or

Here, in S230, specifically, the network device determines the number of coding blocks actually included in the currently scheduled transmission block based on the information of the second number, and determines the number of coding block groups actually included in the currently scheduled transmission block based on the maximum number of coding block groups that can be included in one transmission block and the number of coding blocks actually included in the transmission block.

In an embodiment of the present application, the step of determining the number of coding block groups actually included in the currently scheduled transmission block based on the maximum number of coding block groups that the network device can include in one transmission block and the number of coding blocks actually included in the currently scheduled transmission block includes determining the smaller value of the maximum number of coding block groups that the network device can include in one transmission block and the number of coding blocks actually included in the currently scheduled transmission block as the number of coding block groups actually included in the currently scheduled transmission block.

In an embodiment of the present application, if the currently scheduled transmission block is a transmission block for downstream transmission, the method 200 further includes the network device receiving feedback information from the terminal device, and the network device determining, based on the feedback information, coding block groups that have failed to be transmitted among the coding block groups actually included in the currently scheduled transmission block.

In an embodiment of the present application, if the currently scheduled transmission block is selectable and is a transmission block for uplink transmission, the method 200 further includes the network device sending scheduling signaling, the scheduling signaling indicating retransmission of some coding block groups within the coding block groups actually included in the currently scheduled transmission block.
